TYPE-WRITER CARRIAGE.

SPECIFICATION forming part of Letters Patent No. 752,106, dated February16, 1904.

Application filed March 13, 1903.

justed upon the carriage for the purpose of bringing said platen intoexact parallelism with the direction in which the carriage travels andalso of adjusting the platen bodily, if

desired, and, furthermore, of taking up whatever end play there may bebetween the platensupports.

The invention will be fully described hereinafter and the features ofnovelty pointed out in the appended claims.

Reference is to be had to the accompanying drawings, in which Figure 1is arear elevation of the carriage with parts broken out. Fig. 2 is anend view with parts in section, and Fig. 3 is an enlarged detail view ofone of the platen-adjusting devlces.

A indicates the body of the carriage, which is adapted to travellengthwise of the supporting-rod B. This body is provided with twocircular sockets A, preferably in the nature of clamps, one of thesesockets being located at each end of the carriage. Each socket may becontracted to exert a clamping action by means of a screw C. In each ofthe sockets is mounted to turn a lug D, in which is journaledeccentrically a rodor pin E. Around this pin is fitted loosely orrigidly an eye F, which is located at the rear end of the arms or hooksF, which at their forward ends engage the platen G. The platen alsoengages inthe usual manner aframe H, which in this case is an auxiliaryframe capable of independent movement relatively to the body A. Theauxiliary frame H carries the pawl I, which is Serial No. 147,578. (Nomodel.)

employed to rotate the platen by means of the ratchet-wheel G.

It will be understood that inasmuch as the pin E is eccentric withrelation to the socket A arotation of the lug D will cause the center ofthe platen to be moved forward or rear- Wardthat is, the distancebetween the platen and the supporting-rod B may be altered. Inasmuch asthere are two independent adjusting devices connected with the platen atdifferent points of its length, it will-be obvious that by their aid theplaten can be brought into exact parallelismwith the supporting-rodBthat is, with the direction in which the carriage travels-whichparallelism is essential to a uniform action of the types at everyportion of the platen.

My invention is generally applied to a frontstrike type-Writer, and toillustrate this I have indicated one of the type-bars J in printingposition in Fig. 2. In such a machine a further advantage is secured inthat the platen may be adjusted bodily toward and from theprinting-point in a direction from front to rearthat is, in a directionperpendicular to the plane or face of the type when the latter is in theprinting position. I may thus bring the platen farther to the rear incase very heavy paper or light cardboard is to. be writ-- ten upon.

, I desire it to be understood "that various modifications may be madewithout departing from the nature of my invention.

To enable the lugs or bushings D to be readily turned, I may providethem with flat surfaces D'. In the particular structure shown the twopins E, which fit into the said lugs or bushings, are portions of oneand the same rod, which also constitutes a pivot or hinge connecting twocarriage portions. This, however, is not absolutely essential.

I clairn- 1. In a type-writer the combination of the carriage, arms atthe ends of the carriage, a platen-carrier engaged by said arms, anindependent movable eccentric for connecting each of the arms adjustablywith the carriage to permit of separately changing the distance betweenthe carriage ends and that portion of the platen-carrier which isengaged by the respective arms, whereby the platen may be brought intoparallelism with the path of the carriage.

2. In a typewriter, the combination of the frame having a track, thecarriage-body movable on said track, a platen-carrier held to move Withsaid body, and an independent adjusting device for each end of theplaten-carrier to move the corresponding platen end toward or from thecarriage-track, whereby the platen may be brought into parallelism withthe path of the carriage.

3. In a type-writer, the combination of the carriage, arms having aneccentric adjustable connection with the carriage, and a platencarricrengaged by said arms.

4. In a type-writer, a carriage provided with sockets, lugs mounted toturn in said sockets, pins arranged eccentrically of said lugs, armsconnected with said pins, and a platen-carrier engaged by said arms.

5. In a type-writer, a carriage having clamping-sockets, means forcompressing said sockets, lugs mounted to turn in said sockets, andprovided with eccentric portions, arms connected with said eccentricportions, and a platen-carrier engaged by said arms.

In testimony whereof I have signed my name to this specification in thepresence or two subscribing witnesses.

CHARLES DE LOS. RICE.
